Robey interpolated a sketch into the show based on his music hall character "The Prehistoric Man", with Pollard playing the role of "She of the Tireless Tongue".[2] In another scene, he played a drunken gentleman who had accidentally secured the box at the Savoy Theatre instead of an intended hotel room. The audience appeared unresponsive to the character, so he changed it mid-performance to that of a naive Yorkshire man. The change provoked much amusement, and it became one of the most popular scenes of the show.[3]Zig-Zag ran for 648 performances.[2]
